Energy rating trial helps homeowners improve efficiency and reduce costs
From this week, selected NAB customers applying to refinance or top up their mortgage will be invited to take part in a new Australian Government led energy rating trial for existing homes.
Customers will receive an assessment of their home’s energy performance, giving them a starting point to make improvements that can help reduce energy bills over time.
NAB Chief Climate Officer Jacqui Fox
The trial is part of the Australian Government’s expansion of the Nationwide House Energy Rating Scheme (NatHERS) to existing homes. It is designed to help homeowners identify cost-effective upgrades to improve their home’s comfort and reduce energy usage.
NAB Chief Climate Officer Jacqui Fox said NAB is proud to support the NatHERS for existing homes trial, working alongside the Australian Government, Australia’s national science agency CSIRO, and property valuers.
“Cost of living pressures are still looming large for so many people which is why we’re thinking creatively about how to help Australians save money,” Ms Fox said.
“Energy bills can be one of those variable bills that consumers scrutinise to work out how they can reduce them over time.
“Knowing where to start when upgrading your home is often the hardest part.
“This initiative will help simplify the process by providing participants with practical recommendations such as improving insulation, installing energy efficient appliances, solar, batteries, window coverings, and draught proofing.”
How the trial works:
- The trial will test the tools and processes used to assess the energy efficiency of existing homes, ahead of a national rollout later this year.
- Each assessment will take place at the same time as a property valuation and will take around 30-60 minutes.
- Participants will receive a trial energy rating certificate, plus recommendations on how to improve their home’s efficiency.
- Around 800 NAB customer’s properties will be assessed as part of the trial
